Description

Scalp cone

Technical Field

The present utility model relates to the field of medical devices, and more particularly, to a scalp cone for puncturing the scalp.

Background

Hypertensive cerebral hemorrhage is a disease with high mortality and disability rate among cerebrovascular diseases, and the disease with high mortality and high disability rate is seriously threatening the health of the national population. In addition, there are a very few patients with intracranial tumors, and the occurrence rate of the brain tumor is about 1.9-5.4 people/(10 ten thousand people in year) at present. During the treatment of these diseases, it is generally necessary to conduct an extra-ventricular drainage, in which an intracranial drainage catheter is placed to drain excess blood cerebrospinal fluid or blood clots. For this purpose, it is necessary to drill a hole in the skull to introduce the ventricular drainage tube into the skull, and to puncture the scalp outside the puncture site of the skull before drilling, so that the skull bone under the scalp is partially exposed, so that the drill acts on the skull bone in the region of the punctured scalp.

In current practice, the scalp in the vicinity of the puncture site is scratched off directly with a scalpel before the skull is drilled. However, since the blade of the scalpel is sharp and the distance of incision is long, a long incision is made on the scalp, resulting in a large number of blood vessels located in the scalp being incised, causing problems of excessive bleeding and slow healing of the incision.

In addition, larger incisions are also more prone to infection, increasing the risk of surgery.

Disclosure of Invention

The object of the present utility model is to propose a scalp cone with which it is possible to pierce the scalp at a defined drainage puncture point on the skull and to solve at least one of the above-mentioned problems.

The utility model relates to a scalp cone for puncturing the scalp, comprising a rod-shaped body, on a first end of which a scalp cone head is formed, and on a second end of which opposite the first end a handle is provided, which tapers away from the rod-shaped body into a sharp tip.

By the technical measure of the utility model, a scalp cone capable of assisting in puncturing the scalp is provided.

In an exemplary application, the scalp cone can be used, in particular, in neurosurgery for extracerebral drainage or intracranial hematoma drainage, which can advantageously puncture and prop open the scalp outside the predetermined puncture point of the skull. On one hand, the scalp cone has smaller wound on scalp and smaller bleeding amount, can reduce the risk of bacterial infection of the wound and is beneficial to subsequent recovery; in addition, after the drainage tube is placed, the elastic scalp wound can be tightly wrapped around the drainage tube, blood seepage and liquid leakage do not occur at the scalp wound, and bacteria are prevented from propagating at the wound and invading the cranium. On the other hand, when the scalp is punctured by the scalp cone, the tip of the scalp cone can drill pits corresponding to puncture points marked on the scalp on the skull under the scalp at the same time, so that clear positioning points are provided for drilling the skull in the next step, the drilling positions are stable and have no deviation, and the wound on the scalp and the drilling holes on the skull have no dislocation, thereby being beneficial to the subsequent placement of the drainage tube.

In some embodiments, the scalp taper may be configured as a taper. When the tip of the scalp cone is pierced into the scalp and the scalp cone is further advanced, the piercing opening of the scalp can be naturally opened and expanded with the scalp cone head while being advanced due to the gradually increasing cross-sectional size of the tapered scalp cone head itself toward the rod-shaped body, the operation is simple and the wound on the scalp is small.

In some embodiments, the scalp cone head may be configured as a pyramid.

In some embodiments, the scalp cone head may be formed in a quadrangular pyramid shape having the tip as an apex, wherein the scalp cone head may have a diamond shape in a cross section.

In some embodiments, the minimum included angle between two adjacent sides of the diamond may be between 45 ° and 75 °. The angle is for example about 60. The scalp cone head has a flat diamond-shaped cross section, and two opposite edges of the scalp cone head, where the minimum included angle is located, can apply relatively large extrusion force to the scalp when the scalp cone is penetrated, so that the scalp cone head further helps to open and expand the puncture opening when the scalp is penetrated, and avoid causing tearing injury of the scalp.

In some embodiments, a rounded portion may be formed on each edge of the scalp taper such that each side of the scalp taper smoothly transitions into each other. After the scalp cone head pierces the scalp, the piercing opening can be enlarged by rotating the scalp cone back and forth, and the rounding on each edge of the scalp cone head can avoid further scratching the scalp around the piercing opening to a certain extent when rotating the scalp cone.

In some embodiments, the rod-shaped body may be configured in a cylindrical or prismatic shape.

In some embodiments, the rod-shaped body may have a circular, hexagonal, or octagonal cross-section.

In some embodiments, a rounded portion is formed between the scalp taper portion and the cylindrical surface of the rod-shaped body such that the scalp taper portion and the rod-shaped body smoothly transition with each other.

In some embodiments, the scalp cone may comprise a handle integrally connected with the rod-shaped body. Thereby facilitating the grasping and manipulation of the scalp cone. For example, the two may be integrally formed of materials and welded to each other.

In some embodiments, the handle may be cylindrically configured, or spherically configured, or V-shaped, or pistol-shaped.

In some embodiments, the handle may be a cylindrical handle, and the longitudinal axis of the handle may have an included angle of between 45 ° and 75 ° with respect to the longitudinal axis of the rod-shaped body.

In some embodiments, the longitudinal axis of the handle may have an included angle of 50 ° to 70 °, such as about 60 °, with respect to the longitudinal axis of the rod-like body.

In some embodiments, the handle may have a frosted surface structure and/or at least one ridge and/or at least one groove and/or a plurality of pointed protrusions on the surface for enhancing friction when the handle is held by hand.

In some embodiments, the handle may be connected to the rod-shaped body in a form-fitting manner and/or in a material-fitting manner. For example, in some embodiments, the rod-shaped body may be removably connected to the handle. Alternatively, in other embodiments, the rod-like body may be constructed in one piece with the handle.

In some embodiments, the scalp cone may be made of a titanium alloy or stainless steel. The stainless steel is in particular medical stainless steel. Thus, the scalp cone can have good corrosion resistance and antibacterial property. In some embodiments, the scalp cone may be reused after being sterilized, thereby reducing the cost of use.

In some embodiments, the scalp cone may be configured as a medical instrument assembly with a skull drilling instrument. In other words, the scalp cone is configured as a pilot device for craniotomy. In craniotomy, the scalp acupuncture may be used, for example, with other instruments, such as a cranial burr and/or a needle for puncturing the dura mater.

The technical features mentioned above, the technical features to be mentioned below and the technical features shown in the drawings alone may be arbitrarily combined with each other as long as the combined technical features are not contradictory. All possible combinations of features are specifically described herein. Any one of the plurality of sub-features contained in the same sentence may be applied independently, and not necessarily with other sub-features.

Detailed Description

Exemplary embodiments will now be described more fully with reference to the accompanying drawings. It is to be appreciated that elements not necessary for an understanding of the present utility model may be omitted from the drawings for ease of illustration and understanding. In the drawings, like reference numbers indicate identical or functionally identical elements. In the following description, numerous specific details are set forth, such as examples of specific components, devices, and methods, in order to provide a thorough understanding of embodiments of the present utility model. It will be apparent to one skilled in the art that it is not necessary to employ all of these specific details. The exemplary embodiments should not be construed as limiting.

Fig. 1 shows a schematic view of a scalp cone 100 according to an embodiment of the utility model. The scalp acupuncture 100 may be configured as a medical instrument assembly with a skull drilling instrument. The scalp cone is configured as a pilot device for craniotomy. Here, the scalp cone 100 includes a rod-shaped body 10, a scalp cone head 20 constructed at a free end of the rod-shaped body 10, and a handle 30 provided on the rod-shaped body. The scalp cone 100 can be used, for example, in neurosurgery operation for performing drainage outside the brain or drainage of intracranial hematoma. In use, the scalp cone 100 is capable of puncturing and distracting the scalp with the scalp cone head 20 at a predetermined location to provide a good basis for subsequent operations such as drilling an exposed skull or placing a drainage tube.

The scalp taper 20 tapers away from the shaft body 10 to a sharp tip 21 (see fig. 2) away from the shaft body 20. The scalp can be pierced with the sharp tip 21, and thus the piercing of the scalp can be spread and expanded by the portion of the scalp cone head 20 gradually increasing from the tip 21 toward the rod-shaped body 10 as the head cone 100 is fed. On the one hand, the scalp cone 100 pierces the scalp in a substantially blunt manner, causes less trauma to the scalp, produces less bleeding, is substantially free of bleeding and leakage at the scalp wound, avoids the risk of bacteria propagating at the wound and invading the cranium, and in addition, the smaller wound contributes to subsequent recovery, as compared to the current manner of cutting the scalp in the vicinity of the point of penetration with a sharp surgical knife and causing a relatively long incision. Thus, the blunt separation achieved with the scalp cone 100 is advantageous compared to the so-called sharp separation using a surgical knife. On the other hand, in practice, the desired puncture site is typically marked on the scalp prior to surgery as a reference for subsequent drilling of the skull, whereas the puncture site marking on the scalp may be destroyed when the scalp is scratched with a scalpel, and the longer incision makes the exposed area of the skull larger, resulting in failure to drill the skull in an accurate position. In contrast, when the scalp is pierced by the scalp cone 100, the sharp tip 21 of the scalp cone 100 can simultaneously drill the pit corresponding to the mark position of the piercing point on the scalp on the skull under the scalp, so as to provide a definite locating point for the next step of drilling the skull, so that the drilling position is accurate, the wound of the scalp and the drilling hole on the skull are free from dislocation, and the subsequent drainage tube placement is facilitated. In order to intuitively align the tip 21 of the scalp acupuncture 100 with a desired puncture site. The tip 21 may be located on the central axis L1 of the rod-shaped body 10.

As shown in fig. 3, the cross section of the scalp cone head 20 may have a shape of a rounded diamond 22, so that the scalp cone head 20 forms a quadrangular pyramid shape having the tip 21 as an apex, wherein each edge of the quadrangular pyramid shape is rounded. The minimum angle between

adjacent sides

23, 24 of the diamond 22 may be between 45 ° and 75 °, for example about 60 °. The scalp cone head 20 thus has a flat diamond-shaped cross section, and the two opposing edges 26 (see fig. 2) at which the minimum included angle of the scalp cone head 20 is located can exert a relatively large compressive force on the scalp when the scalp cone 100 is pierced, which further helps to open and expand the puncture site when the scalp is pierced, and avoids causing lacerations to the scalp.

Rounded portions 25 are formed on four edges of the scalp cone head 20 so that there is a smooth transition between the respective sides of the scalp cone 20. After the scalp cone head 20, particularly the tip 21, pierces the scalp, the piercing opening can be enlarged by rotating the scalp cone 100 back and forth, and at this time, the rounded portion 25 can avoid cutting the scalp around the piercing opening to some extent when the scalp cone 100 is rotated, thereby enlarging the piercing opening more gently.

As shown in fig. 1, the rod-shaped body 10 may be configured in a cylindrical shape. A rounded portion may be formed between the scalp taper portion 20 and the cylindrical surface of the rod-shaped body 10 so that the scalp taper portion 20 and the rod-shaped body 10 smoothly transition with each other. Thus, damage to hair follicles can be reduced, and the probability of bacterial invasion to wounds can be reduced. Alternatively, the rod-shaped body 10 may be configured as a rod having a hexagonal or octagonal cross section.

The cylindrical handle 30 may be arranged transversely to the shaft body 10 at the end of the shaft body 10 opposite the scalp cone head 20, and the longitudinal axis L2 of the handle 30 may have an angle of between 45 ° and 75 °, preferably 60 °, with respect to the central axis L1 of the shaft body. Thereby facilitating gripping and force application. Naturally, the handle 30 may also have any other structural form suitable for gripping and manipulation, for example, being configured as a sphere, V-shape, gun handle, or the like. For example, the handle 30 may have a concave-convex surface adapted to the finger. In order to increase the comfort of use, structures for increasing friction may also be constructed on the surface of the handle 30. For example, the handle 30 may have a frosted surface texture and/or at least one ridge and/or at least one groove and/or a plurality of pointed protrusions to avoid undesirable consequences of the scalp orientation cone 100 slipping off during use.

The wand body 10 may be detachably connected to the handle 30, for example to facilitate replacement or cleaning. Alternatively, the rod-shaped body 10 may be constructed in one piece with the handle 30, for example integrally connected by welding.

The scalp cone 100, and in particular the rod-shaped body 10, may be made of a titanium alloy or stainless steel, in particular medical stainless steel, such as martensitic stainless steel. So that the scalp cone can have good corrosion resistance and antibacterial property. The rod-shaped body 10 and the handle 30 may be made of the same material or different materials.

The scalp cone 100 is particularly advantageously constructed to be reusable so that the scalp cone 100 can be reused after being sterilized in order to reduce the use cost.
